ROBERT S. BROWN, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE NEW BRITAIN MACHINE OOMPAN Y, OF NEW BRITAIN, CONNECTICUT,

CUT.

A CORPORATION OF CONNECTI- W'HEELED TRUCK.

T 0 all whom it may concern:

Be it known that 1, ROBERT S. BROWN, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful improvements in \Vheeled T ruoks, of which the following is a specification.

This invention relates to wheeled-trucks.

A truck comprising my invention may be employed with advantage in many different connections; for example it may be utilized for supporting tools of various kinds.

I employ the title wheeled-truck si ply for convenience and also for the fact that the truck is referably sustained upon wheels by virtue 0 which said truck can he moved from place to place in a shop or other establishment with ease and facility. Some of the features of the truck may be utilized without the necessity of em )loying Wl'lOBlS in connection therewith. In like manner certain of the features of the invention may be separately used it is not necessary that they be joined together in one apparatus.

In the drawings accompanying and forming part of this specification I represent in detail one effective form of embodiment of the invention which to enable those skilled in the art to )ractice the same will be set forth in detail in the following description While the novelty of the invention will be included in the claims succeeding said description. I wish to make it clear that I do not restrict the invention to the showing thus made for certain variations may be adopted within the scope of my said claims.

Referring to said drawings, Figure 1 is a perspective view of a truck including my in- Fig. 2 is a top-plan view of a pair vention. of cotiperating rockers or oscillatory carriers, the base of the truck being shown in said figure and in section. Fig. 3 is a side elevation of the truck, with portions thereof broken away and in section to more clearly il ustrate certain parts and in said figure a portion of the truck-body is broken away from the remainder thereof and with certain adjunctive members is thrown around to more clearly represent the latter. Fig. 4 is a sectional view of parts of the base, trays, crown-piece or top, and a connecting rod, on an enlarged scale. Fig. 5 is a horizontal section of the body. Fig. 6 is a detail view of Specification of Letters Patent. Application filed May 22, 1908. Serial No. 434,222.

Patented Dec. 22, 1908.

the carrier or rocker operating means, a portion of one of the rockers appearing. Fig. 7 is a detail View in section on the line 7-7 of Fig. 6, of latching means, and, Fig. 8 is a sectional detail view hereinafter more particularly described.

Like characters refer to like parts throughout the several figures.

The truck involves in its make-up a base member which may be of any desirable char actor; for instance it may consist of a shell as 2 which has a foot-flange as 3 at its lower end or bottom of annular form and externally thereof. This flange when the truck is not sustained by its wheels hereinafter described, is adapted to rest on a floor and it provides an ample bearing for the truck; that is the flange provides a means for maintaining the truck solidly and substantially in an upright condition. This base member 3. may be of any suitable material, for example it may be made by casting. The body of the truck in like manner may be of any suitable material, sheet metal answering my pur )ose. The body illustrated is denoted by 4 an it is of part cylindrical form. T 0 make the body I take a sheet of metal of required area and shape or bend it in some suitable manner to produce the desired ob'ect. Preferably the lower edge of the hotly sets in a circular groove as 5 in the base member .2 while the upper edge thereof fits a similarly shaped groove as 5 formed in the under side of a top or crown-piece as 6. The top or crown-piece and base member 2 are tied together in some suitable manner as by one or more rods or bolts as 7 and by thus tying together such two parts I securely retain in position. against lateral and circumferential motion, the part cylindrical body 4 and do not have to em ploy extraneous fastening means for holding the body in position. T here may be any de sired number of these rods or bolts as 7, their upper ends being tapped in the underside of the top 6 and their lower ends extending through perforations in an inwardly-extending annular flange as 8 at the upper end of the base 2 and receiving nuts as 9 fitted in downwardly tapered counterborcs as 10 in the under side of said flange thereby holding said rods in place and the top and base in assembled relation. l prefer not to rely wholly on the nuts 9 to obtain the function just set forth but will surround the nuts by a locking means such as a mass of Babbitt T metal 11 in each case which is poured into 1 the respective bores 10 to bottom therein and l to surround the respective nuts. Such 5 metal when cold prevents the turning of the l nuts from the lower ends of the rods 7and l by taperin r said bores the Babbitt metal will be retained in place. This construction also insures against the surreptitious removal of the rods should this ex edient be adopted to obtain access to the b0 y 4 when the latter is locked closed, all of the rods being as is clear inclosed by the body 4. Said body 4 is also shown as having several trays all of the same general character for which reason each is denoted by 12. The trays 12 are substantially circular and fit comparatively closely within the body 4, each having several holes therethrough for the passage of the tie rods or bolts 7. The trays have a sliding movement on the respective rods to rovide for adjustment and they may be hel in their respective adjusted positions in any desirable i manner, for illustration by means of screws as 13 threaded therethrough and the tips of which are adapted to engage one or more of the rods 7 for the purpose set forth. The top 6 also presents a tray although it is of greater superficial extent than the interior trays 12 and it has flanges as 14 along two ends and a side thereof to prevent the dislodgment therefrom of any tools which may be thereon, the flanges presenting in effect a continuous guard-bead to attain the result in question. The top 6 has no flange along the side thereof in the foreground in Fig. l, a vise as 15 being attached to this side of the top between the end flanges thereof. This brings the vise in a position approximately centrally between the forward opening of the body, here'mafter referred to, and the solid back of said body so that the downward thrust exerted by a user of the vise is not applied to the top 6 over the said opening but is applied to substantial stock of the body or at a point where the latter is best calcuiated to resist said thrust. The top 6 can be utilized for supporting various kinds of tools and work whi e the trays 12 can be used for the same pur ose.

'1 1e body 4 has an o ening or doorway as 16 at the front thereof y which access may be had to the interior of said body 4 for the purpose of putting tools or work on any one of the superposed trays 12 or for removing the same therefrom and this opening or doorway may be closed when desired by a door as 17. When said door is shut it ma if necessary be held in such relation une-r lock and key. The door cross sectionally is of circular form, its width being somewhat greater than that of the openin 16 whereby when closed it can overlap theiody 4 adjacent the opening. In the present case said door is sup-ported for swinging movement by the top 6 and the bottom tray 12 as I will hereinafter describe and in addition to this it has a sliding movement on the flange 8 and against an upwardly-rising guide as 18 on the base 2. omplemental to said flange 18 is a flange as 1.) depending from the under side of the top 6, both said flanges as will be obvious being of arcuate form.

The door 17 is represented as provided on its inner side with inwardly-extending arms 20 and 21, the lower arm 20 receiving a pivot pin as 22 pending from the bottom tray 12 and the u per arm 21 receiving a substantially simi a1 pivot as 23 )ending from the top 6, the two pins being sliown as vertically alined and as extending through the inner ends of said two arms, the latter being rigidly united at their outer ends to the door 17 at or near one edge thereof. In Fig. 1 the door is represented as being open while in Fig. 5 it is shown as closed and when closed it may be held in such relation by a lock, the flanges 18 and 19 to which I have previously referred, preventing the passage of a tool either above or below the door while other means hereinafter described, subserve a like function with respect to the sides of said door.

Upon the outside of the body 4 adjacent to one side of the door-way 16 I fasten in some suitable way as by rivets a strip 24, the length of which equals that of the door 17. This strip therefore extends the complete height of said door-way and is very close to one side wall thereof; it coacts with a sub stantially similar strip as 25 of the same length fastened to the inside of the door along one of the side edges thereof, both strips being as will be a iparent of practically the same length and they are adapted to interlock as shown in Fig. 8 when the door is closed, for which purpose said strips are op positeiy curved, the strip 25 when the door 1s closed fitting in the space between the strip 24 and the body 4. It might be well to state that While the body 4 and door 17 are both circular, the door is upon a greater radius than that of the body so as to provide for a space between the two in which these interlocking strips can be located. Upon the body 4 and in proximity to the door-way at that side thereof op osite that near which the strip 24 is locate is a strip or head as 26 which on the side thereof next the door 17 is provided with a channel as 27 to receive said door when the same ,is closed. Upon the outside of said strip 26 is a staple or screweye as 28 cooperative with a has as 29 on the door and the presence of w-hici provides a means whereby, with the aid of a lock (not shown) the door 17 can be locked closed. In addition to this the hasp 29 acts as a means for easily manipulating the door 17 to either open or close the same. The strips 24 and 26 extending as they do along opposite sides of and adjacent to the door-way 16 act as reinforcing means for the body 4 and re vent possibility of the same buckling w ien downward strain is applied thereto while using the vise 15 or whi e the top 6 is being em oyed as a work table or bench.

he foregoing is a detailed description of a device which could be used as a stationary tool-cabinet, vise-stand or similar article. I prefer, however, to use in conjunction with said device, wheeled supporting means whereby the device can be transported without any trouble or effort and I will now describe the means shown for obtaining portability of the apparatus, and such means is of such nature that the truck as a whole can be easily turned or swung around corners.

I have shown as depending from the flange 8 near the forward side thereof bearings or brackets as 30 which receive for oscillation pintles as 31 on the rock-shaft 32. Between the ends of said rock-shaft 32 is a forwardlyextending arm as 33 and near one end thereof is the rearwardly-cxtending arm 34, the said shaft and the two arms presenting a rocker or carrier for the truck. The arm 33 receives for turning movement near its front end an upright spindle as 35 provided with an axle as 36 for a pair of wheels as 37, such wheels serving as swiveling wheels for the truck.

Near the rear part of the base 2 is a transverse row of bearings all designated by 38 which support a fixed. shaft as 39 which constitutes a pivot for a pair of arms as 40, the shaft extending through said arms near the front ends, said ends being joined by a bridgepiece as 41 from which there extends a bent projection as 42, the two arms 40 and the ridge-piece 41 presenting a yoke-like rocker or earner cooperative with the other carrier to which I have already referred. The projection 42 cooperates with the arm 34 although in the present instance there is not ordinarily a direct engagement between the two. I have shown tapped through the arm 34 from the under side thereof, a screw as 43 constituting a suitable adjusting device, the u )per end of which bears against the forwar end of the projection 42 to relatively adjust the two rockers both ofwhidh as will be apparent turn about axes between their ends.

The arms 40 carry an axle as 44 which is preferably fixed, and this result can be secured by the aid of a screw as 44 tapped through one of said arms and engaging the axle 44. The latter is provided at its opposite ends with wheels as 45 of larger diameter than the swiveling wheels 37 although this particular relation is not nccessar The rockers operate against eac 1 other between their centers or axes of movement and their wheels are carried outside said centers from which it will be apparent that said rockers can be so u )erated as to permit the truck or that part thereof including the base 2 and what is above it being raised. from off a floor when it is desired to move the truck from one place to another or to permitsaid truck to rest solid on the ground or to be s11)- )orted by said base 2 when the truck should e at rest. In the resent instance the raising and lowering o the truck is effected by the application of power to one of the rockers and the rocker thus operated. serves to actuate the companion rocker to attain the desired result, and the means shown for this will now be set forth.

Upon the rear side of the body 4 at a suitable height thereof, I fasten in some suitable manner a bracket as 46 and iivot to the same an arm or lever as 47, the latter having a handle as 48 at its free end to facilitate its operation. To the lever or arm 47 near'the pivot thereof l prefer to joint a socket-piece as 49 into which is threaded the upper end of a rod as 50 which with the socket piece presents a connecting link that is adjustable as to length, the adjustment being maintained by a check nut as 51 on the rod. Said rod extends through a perforation near the tail of the arm 34 and terminates in an enlargement as 52 which. engages against the under side of said. arm 34.

In Fig. 6. the lever 47 is shown as occupying the position it assumes when the base 2 is resting upon a floor or like support the several wheels 37 and 45 being at this time out of action although their rims touch such floor or they may be slightly above the same. To put the wheels in action which is done by the elevation of the base 2 the arm 47 is swung to the right in Fig. 6 until it has assumed a position corresponding substantially to that it is shown as occupying in F 3. During the swing of the lever the socket piece 49 and. the rod 50 acting as a link will be elevated thereby through the intermediate parts lifting said base 2 from off the floor. As the rod 59 is elevated the arm 34 is lifted thereby the arm 33 being lowered. By reason of the action of said arm 34 through the screw 43, against the projection 42 the latter and hence the forward branches of the arms 40 are elevated while the rear branches of said arms 40 are lowered, whereby both sets of the wheels can. be put simultaneously into action. The arm or lever 47 and the cojperating socketpiccc 49 and rod 50 act as a toggle so as to reduce to the minimum the power necessary to put said wheels into use, the same being further aided by the length of the said arm 47. I. might use this toggle d vice as a means for locking the wheels in their operative relations but prefer not to do so as jars or shocks might disturb the same, tl'irowing the toggle off center and permitting the base 2 thereby I to descend. To eliminate such a possibility 1 as this 1 provide means of a positive kind to lock the rocker-operating means in the shifted position thereof and that shown for this purpose will now be described.

Upon the bracket 46 l have shown a pivoted latch 53 normally held in its working relation by a coiled spring as 54 fitted in a socket in said bracket and bearing against the latch. hen the arm or lever 47 has completed its shifting movement or that it takes in raising the truck the shouldered portion of the latch is snapped over said arm or lever 47 by the power of the spring 54 to lirml y retain said arm or lever in said shifted )osition. The arm or lever can be easily released to lower the base 2 or the truck of which said base forms a part, by disengaging the shouldered portion of the latch from the arm or lever by power applied to the tail of said latch.

The members 49 and. 50 as is apparent are adjustably connected whereby the time of engagement of the wheels of the truck, with the ground can be regulated independently of the throw of the hand lever 47.
